Effect of ERK inhibitor on pulmonary metastasis of inoculated human adenoid cystic carcinoma cells in nude mice

In this study, we detected the expression of phosphylated ERK1/2 in human salivary adenoid cystic carcinoma (SACC) by immunohistochemical method, the effect of various concentrations of PD98059 on the growth of ACC-M cells (a cell line of human adenoid cystic carcinoma of the salivary glands) by MTT assay, and the effect of PD98059 on the lung metastasis of inoculated ACC-M cells in nude mice. The results showed that the phosphylated ERK1/2 was overexpressed in SACC, the ACC-M cell line proliferation was inhibited by PD98059, and the lung metastasis level was reduced by PD98059, indicating that ERK may be a key molecule in targeted therapy of adenoid cystic carcinoma.
